Design of desktop 3D printer control system based on ARM
The desktop 3D printer control systems with a sigle-chip controller have problems of slow processing speed, more pieces of outside chips, circuit complexity and poor quality of printing.To solve these problems, a desktop 3D printer control system with an ARM controller is designed.The system employs the LPC1768 microcon-troller based on ARM Cortex-M3 core which is introduced by the NXP and used to communicate with the host com-puter, data processing, analog acquisition and processing, signal control, used A4988 special two-phase stepper motor driver to implement stepper motor subdivision drive and to simplify the drive design for stepping motor.The travel switch circuit adopts GK152 infrared photoelectric sensor.The software adopted PID method in order to adjust the heating temperature of heating bed and extruder.This paper discusses the main hardware circuit design and soft-ware realization process of the control system.The System testing shows good performance.
